Background: Nutritional supplementation is widely used to support physical and cognitive performance in football. However, evidence on multi-ingredient protocols combining taurine, caffeine, and phosphatidylserine (PS) remains limited in professional athletes. Methods: Eighty-one professional male football players (19–32 years) were randomly assigned to three groups (n = 27): placebo (P), taurine + caffeine (TC; 1500 mg taurine + 200 mg caffeine), and taurine + caffeine + PS (TCP; 1500 mg taurine + 150 mg caffeine + 300 mg PS) in a randomized, placebo-controlled, single-blind trial. Supplementation lasted 10 days, with a final dose administered 60 min before a standardized 105 min training session. Reaction time, sprint performance, GPS-derived variables, and technical/tactical indicators were assessed. Data were analyzed using ANOVA with post hoc tests, and pairwise comparisons were additionally adjusted using the Holm–Bonferroni correction due to the exploratory nature of the analysis. Results: Compared with placebo, the TCP group was associated with more favorable physical, cognitive, and selected game-related outcomes (p < 0.05). TCP was associated with higher locomotor performance (η² = 0.13–0.20) and smaller fatigue-related declines in sprint performance (−18% vs. −34%) and speed (−10% vs. −19%) (η² = 0.18–0.22). Reaction time and technical indicators, including passing accuracy (84% vs. 75%) and dribbling success (73% vs. 62%), were also improved. Higher coach-rated tactical performance scores were observed in TCP (η² = 0.19–0.25). Conclusions: A short-term multi-ingredient protocol including taurine, caffeine, and PS may be associated with improved physical, cognitive, and selected game-related outcomes in professional football players. However, due to differences in caffeine dosage between groups, the independent effect of PS cannot be determined. Further double-blind studies are warranted. Given the exploratory nature of the analysis, the multiple assessed outcomes, and the partly subjective coach-rated tactical evaluations, the cognitive and tactical findings should be interpreted cautiously and regarded as preliminary rather than confirmatory evidence.

Nutrition acts an important role for soccer players as it provides energy and affects recovery after training. Objective: The aim of the study was to assess the method and quality of nutrition of young football players and the impact of nutrition on VO2max, power, heart rate and somatic parameters. Results: The obtained results indicate that with the increase in calories and nutrients, the percentage of water in the body decreases. In other cases, increasing the amount of calories consumed is associated with an increase in BMI, fat content, lean body mass and muscle mass. VO2max did not correlate with any of the dietary parameters as did the number of breaths per minute. Heart rate results in most cases, when correlated with dietary parameters, produce an inversely proportional fit. Resting heart rate (HR) correlates with eight of the eleven deictic parameters, giving a level of compliance in the range of -0.48 to -0.73. In the case of the size of the change in heart rate after exercise, its size is greater the more calories and nutrients are consumed by the test subjects. These correlations are then proportional. These results range from 0.52 to 0.75. Conclusion: It is not the amount of calories consumed, but mainly carbohydrates that influence the weight of soccer players. On the other hand, the amount of calories and proteins consumed have an impact on the maximum power generated by players. The diet used by the players does not affect their VO2max and the number of breaths per minute, and the amount of calories and carbohydrates consumed affects the recovery time of the circulatory system (heart rate decrease) immediately after exercise.

Background/Objectives: Cognitive fatigue and impaired psychomotor function may contribute to reductions in football-specific performance during prolonged match-like activity. This study evaluated cognitive, psychomotor, sprint, and football-specific locomotor responses to multi-ingredient protocols containing taurine, caffeine, and either 300 or 600 mg·day⁻¹ of phosphatidylserine in professional male football players. Methods: In this randomized, triple-masked, placebo-controlled, parallel-group trial, 97 professional male football players were allocated to placebo (PLA, n = 24), taurine plus caffeine (TC, n = 24), taurine plus caffeine plus phosphatidylserine 300 mg·day⁻¹ (TCP-300, n = 24), or taurine plus caffeine plus phosphatidylserine 600 mg·day⁻¹ (TCP-600, n = 25) for 14 days. Taurine and caffeine doses were 1500 mg·day⁻¹ and 200 mg·day⁻¹, respectively. Outcomes included 30 m sprint performance, visual and auditory reaction time, Stroop-task performance, perceived mental fatigue, GPS-derived locomotor variables, and post-intervention first-to-second-half performance-loss indices during a standardized football-specific exercise protocol. Results: The baseline-adjusted ANCOVA demonstrated a significant treatment-group effect on post-intervention 30 m sprint time. After Holm–Bonferroni correction, significant treatment-related effects remained for Stroop reaction time, visual reaction time, and perceived mental fatigue. No statistically significant treatment-related effect was observed for auditory reaction time (unadjusted p = 0.074; Holm-adjusted p = 0.096). During the post-intervention standardized football-specific protocol, baseline-adjusted GPS-derived locomotor outcomes differed significantly between groups. First-to-second-half performance-loss indices also differed between groups, with the smallest post-intervention losses generally observed in TCP-600. Because comparable decline indices were unavailable at baseline, these findings do not represent intervention-related changes in fatigue resistance. Conclusions: Under the present 14-day experimental conditions, the multi-ingredient protocols containing taurine, caffeine, and phosphatidylserine were associated with more favorable selected cognitive and psychomotor outcomes, 30 m sprint performance, and baseline-adjusted GPS-derived locomotor outcomes than placebo. The groups also differed in post-intervention first-to-second-half performance loss during the standardized football-specific protocol. Because corresponding decline indices were not assessed at baseline, these findings do not demonstrate an intervention-related improvement in fatigue resistance. Numerically more favorable values were observed for several outcomes in TCP-600; however, differences between TCP-300 and TCP-600 were modest and not consistently statistically significant, and the study was not specifically powered to establish a dose–response relationship. Because phosphatidylserine was not tested independently, these findings should be interpreted as responses to the combined multi-ingredient supplementation protocols rather than as effects of phosphatidylserine alone.

Introduction: As overweight and obesity have become a disease of civilization, more and more people try to accelerate weight reduction in various ways. One of the methods used is the use of dietary supplements. Methods: 30 overweight or obese people took part in the study. At the beginning and at the end of the study, each participant was measured and weighed on a professional Tanita DC-360 body composition analyzer. The age in both groups was similar - the average was about 37 years old, height and weight in the group of men was greater. The subjects used the dietary supplement for 6 weeks. At that time, they did not take any other dietary supplements, followed the diet as before, did not consume caffeine and did not undertake any physical activity at that time. Results: There were significant differences in the results between men and women for the field of physical. Women had a significantly higher result, which means that they were more susceptible to the effects of supplements. Individuals who achieved a weight loss score significantly higher for the field of physical. It also turned out that although weight loss and the absence of gastrointestinal problems during supplementation were observed in both groups, they occurred in a greater amount in women than in men, and the differences these were statistically significant. Higher effectiveness among women may be the result of differences in the functioning of the endocrine system, although it is certainly worth taking a closer look at this issue. 40% of respondents did not notice any weight loss while taking supplementation. Conclusions: Plant-based supplements reduce body weight and metabolism, and may also alleviate gastrointestinal discomfort. In addition, they improve digestion in general, increase vitality and, to a small extent, may contribute to the improvement of the immune system.
